more electric control panel questions
When removing old panel, labelled a bare wire to the frame as 12V. Having my doubts. Is it 12V or 120V ground? I suspect it is a needed 120V ground. My mental picture is a loose 120 hot wire laying...

Yes both 12v and 120v ground to the frame. The TT brakes use the frame as the neutral but hopefully the TT is not plugged in while it's going down the road....
One of the hazards of RV wiring is the mix of 120v residential and 12v automotive. In 120v residential, the wiring standard is black/red/any color is hot, white is neutral and green/bare is ground. In 12v auto, the standard is white/any color is hot, black is neutral, no separate ground needed.
So Black can be either hot or neutral depending on whether it's on the "high side" or "low side" wiring.
